Wow 4x BB grids that was hardcore! I had 2 in my loft stacked facing ESE from 85 to 88 until I managed to persuade my parents to let me put one of them outside on a rotator... it was joined by a 6 element B3 a few months later. I had AFN Soesterburg A80 several times between 88 and 91, not all my tuners went up that high but my JVC managed it as did one of my D100s. There was also an AFN outlet in Belgium on CH34 that used to come in occasionally too I think it was at the SHAPE headquarters in Casteau. I had both AFNs on 13/7/90.

Can't help you with the name of your Polish CH36 TX, maybe ask Garry Smith?

Looking at your 1990 logs I had DDR on March 8th too but only on B3 chs E5 and E12.

Thanks for the info Andy - FMList puts it as exactly 1200 km. RMF FM on 93.3 comes from that site.That is the furthest tropo distance I've had on Analogue TV. The best FM tropo distance was also 1200 km - from Sweden (SR P4 Kisa) in October 2015 and in 2017 tropo from Poland (Lebork) on FM at 1173 km.
